gii_cmd_event — LibGII commands and information events
#include <ggi/events.h>
#define GII_CMD_DATA_MAX (248-sizeof(gii_cmd_nodata_event))
typedef struct gii_cmd_event { COMMON_DATA; uint32 code; uint8 data[GII_CMD_DATA_MAX]; } gii_cmd_event;
These are used internally either to the application or the kernel. The same event is used for both Command and Information events.
gii_cmd_event is the basic structure for evCommand and evInformation events. It may need to be casted to some other structure (depending on code) to access the data.
The command or request code.
Provides raw access to the device and/or command specific data. The recipient must not store references to the data. If the data information is needed afterwards, copy it!
One use of evCommand is to convey some capabilities of a GII device, via the GII_CMDCODE_GETDEVINFO command code.
